! in checkInformation(): extended "else" scope from "if selectedInfoID == null" till the end of all checking
# missing content error is now handled in checkInformation() which from now on returns only the selectedInfo

! fixed bug in AuthorSystemContent model's getUnitByUUID()
+ added context info removal function to Unit model
# in formatSelections: made formatUnitIcons() more compact, self-contained and generically usable
# simplified loadUnit() in unitController, applying new functions formatUnitIcons() and addMetaDataToUnit()
- removed activateFunctionalities() and activateContextConfirmation()
# moved contextTab-specific event handlers from generalTabController to contextTabController
# replaced returnArray from checkInformation() with object
# replaced value of "id" in array_multiSelectionContextInfos (multiple infos of same type possible)
TODO: multiContextSelection still troublesome with new kind of IDs, needs to be revised!
TODO: compactify "all" or "one" design rendering code

+ added function to get unit from entire author system content by its UUID
- in contextInfoModel: removed unnecessary complexity in value object
+ in contextInfoModel: added each part of former value object as context info property + getter and setter functions for each
# completed changes towards consistent usage of models: contextInfo, parameters, unit, authorSystem
# completed changes in checkInformation(), drawing information from model structure instead of view
# renamed parameter input and select fields and divs with generic ID "parameter"+i and "divParameter"+i, resp.
# untangled event handlers for clicked or dragged units and properties tab from "blob" activateFunctionalities()
# replaced (use and function of) global var global_currentInputUnitName with global var currentUnitUUID
# made variable currentConnectionID global

# renamed divContextParameters (+ temporary changes in index.hmtl, will be overridden soon)
- removed metaData tab which was a mere placeholder for Tom's CMS work
+ added metaData dictionary
+ added functions addMetaDataToUnit() and removeMetaDataFromUnit()
# changed parameter access and collection in contextInfoController and locationInfoMapController
# moved "get current unit dictionary" code into function getCurrentUnitDataModel()

# minor changes before *the great parameter refactoring* i.e. generification, type checking, value checking, ... (to do)

- removed redundant local variable "name" from activateFunctionalities(), replacing occurrences with global_currentInputUnitName (equal to "name" after unit is clicked)
! fixed minor bug: unit names are now displayed in menu instead of "undefined"

# renamed reloadController.js authorSystemController.js
+ added two fake parameters to measurable-context-information.xml for testing
# moved cleanSections() to tabs.js
+ tried to make #selectOperator invisible on showDetailedContextInfo
# simplified context class color selection
# moved some functionality around so that nothing works anymore... (to be undone)

# un-refactored (in parts) overall project structure: removed (yet) hardly used modalWindows files, added controllers files
# updated (as of yet unsued) contextInfoModel
# put several pieces of functionality in their (for now) right-er places, like e.g. addUnitToScenarioModel(), addUnitToMenu(), ...
- removed redundant replaceMarker2()
+ translated enums in contextTab filler

# transferred translations from contextInfoList to where they're rendered (translations belong to view, not model)
# started on dictionaries for translations and icons

# changed usages of old array_contextInformations (now contextList; using key identifiers instead of indices)
# serialized whole process (before: async), starting from main.js
# updated ContextInfoList structure description (comment): from array of arrays to array of objects

# [xmlParser] transformed array_contextInformation into more easily accessible object (renaming and cleaning up a little, while at it)

# refactored functionaliies.js into reloadController.js (comparison: function preserved)
# in reloadController.js: changed jQuery.ready into jsPlumb.ready due to delayed inst initialization
# simplified metaIcon choice and adding
# moved more code from general (tabs, modalWindows) to more specific files (metadataTabView, createScenarioModalWindowView, ...)
+ added propertyTab.js
- removed several unnecessary files from MVC scaffold

# further refactoring toward MVC
