# adjusted getParameterInput() to changes in DOM

# in locationInfoMapViewController: some minor changes to make map work again

+ in contextTabController: added fillOperatorSelection() --> consistent with fillInputField() and fillOperatorSelection()
# in contextTabController: corrected test: operator == "NO_VALUE"
# in contextTabController: adjusted test if multiple context infos > 2 then show "all or one" selection
# in contextTabController: made formatMultiContextInfosElements() process one item, not all
# in contextTabController: for each fill.*() function check for chosen value/operator (i.e. if this is in edit mode) and render fields/selections accordingly
- in contextInfoController: removed test for "Error999" (i.e. context info added more than once)
# started overhauling locationInfoMapViewController --> TODO: check if it works in edit mode

# 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()

# 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

# 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
