Key graph features (#704)

* Added IGraphAnalyzer

* Key Graph Features called and getting returned to the client. To do put all strings into the Equation object

* Updated UpdateKeyGraphFeatures to add function analysis data to all properties in Equation object

* Update KGF when variables are updated

* Key graph features ui started

* Added MathRichEditBox and started hooking up key graph features to the UI

* Updated EquationViewModel to include parity and periodicity

* Updated key graph features to update the EquationViewModel

* updated key graph features to display more values

* Key graph features populating uing MathRichEdit mode

* moved KeyGraphFeatures control to GraphingCalculator.xaml

* Use MathML formatting instead of MathRichEdit for strings passed back from the engine

* cleaned up project targeting and equation.h comments

* Updated equation edit box to populate for KeyGraphFeatures

* Fixed vcxproj files to have the correct targeting and certificates. KGF Title strings moved to x:Uid instead of the code behind

* Updated per PR feedback

* Update MathRichEditBox to detect if the string is a mathml string and use the appropriate set method to set the text

* fixed the issue where parity, periodicity and monotonicity could be set with an old value if the next one is empty

* KGF control UI adjustments and error handling

* Error control updates

* Error handling added when analysis fails

* fixed alignment on rich edit boxes

* Add monotonicity direction into the mathml string and only have 1 richeditbox

* Set hover state on KGF EquationEditBox to change button opacity and fixed spacing in Monotonicity RichEditBox

* remove sideload package certificate info VS added

* updated logic for setting error strings to be in the viewmodel

* Updated KeyGraphFeatures to populate dynamically using a ListView and TemplateSelector

* Update periodicity to not show if it isn't supported

* Fixed issue where y-intercept was using the x-intercept value

* Remove ItemsControl ItemsContainerStyle

* Updated per pr feedback. Fixed bug where analysis error would not reset

* Update MathRichEdit box to remove selection when focus is lost

* Updated mathrichedit to get LAF access for Dev, Release and Graphing projects

* Remove OnLostFocus in MathRichEdit, Change KGF ItemsControl back to ListView

* Clean up styles for KGF and ensure the match the comps

* Moved formatoptions logic to the Grapher constructor and reverted LineColor.Text resource that was mistakenly taken out

* Add copyright header to KGF Files

* fixed issue where asymptote values were not populating

* Disable KGF button when there is no equation. Fixed issue where equation populated in a new equationtextbox after the previous one was deleted

* Removed formatoptions testing lines used for debugging
