changed: gridMng.view ajaxCreateDendogram so it will save the svg to a
file so it can be tested
changed: all the calls to create an svg text now have the offset
(wordSize[1] - 4) (meaning: word height - 4px) in drawDedogram3. This is
to be able to align the text correctly with the rest of the components
in the svg picture
changed: added the shadow back to the dendogram
added: in rgt.grdMng.view the dendrogramTo function, this function will
send to the user a dendrogram as a file (svg, etc)

used to send a request to the server to download a svg as a file

saveItemAsArguments and saveItemAsUrl
changed: all the functions in svgDendogram are in the process of being
removed as they are not needed anymore
added: imageData class

Asking the site to download a svg is not working atm, functions are
still change to accommodate the changes in the server (full svg support)
changed: renamed imageData to fileData, also added fileName to the class
renamed: ajaxSaveSvgPage to ajaxGetSaveSvgPage

	1. 2 different functions were being set to the save button
	2. downloadItemAs was using the wrong url to get the svg send form
	3. downloadItemAs was not setting the correct url to be used in the svg
send form

__convertSvgStringTo__ and createFileResponse functions
changed: dendrogramTo is now using createFileResponse
added: createFileResponse in rgt.gridMng.util, this function create a
response for a file

adding the svg to the document
WARNING THE DATA IN THE DENDOGRAM COL MUST BE SET TO NULL

added: generalUtil in rgt.gridMng.resonse.xml
changed: createSvgResponse so now the extraData can handle a document or
node
changed: ajaxGenerateSessionDendrogram in rgt.gridMng.session.views so
it will now use the svg xml response.
changed: showSessionDendrogram in mySessionsContent.js 
	1 to handle the svg xml response
	2 to use the new saveItemAs function in the svg menu

attribute to the saveAs svg menu
changed: svgDendogram.js, removed all of the old code
removed: static/js/svg, as this library is not used anymore
changed: ajaxGenerateDendogram in rgt.gridMng.views, removed the test
code

rgt.gridMng.response.xml.generalUtil
added:test code to ajaxGenerateDendogram
added: convertGridTableToSvg, __createSvgTable__ and __TableData___ in
rgt.gridMng.util

Start working on creating functions to convert a grid into svg

This addresses the enhancement in issue #18. This code can be run from the command line. Since this is a prototype, it should only be used as a starting point for implementing PCA.
