Replace incomplete csdgmAliases with module parsed from complete text file

[JeffJacobson]

Parse the reference/csdgm.txt file into JSON to get complete list of elements. This can be used to replace the csdgmAliases.js file.

1. Read text line by line.

2. Use the regular expression see if the current line is the first line of an element definition.

   // Matches first line of element definition
   var firstLine = /^\s*([\d\.]+)\s+(.+)\s-+\s(.+)/;
   /* [
       entire match, 
       element index number, 
       element long name, 
       description (until line break)
      ]
   */

3. Lines after the first line of an element definition are a continuation of the description from the first line.

4. The description stops when a line starting with (not including spaces) Type: is encountered.

5. The Short Name: line indicates what the XML nodes name will be.

6. Keep reading lines until another "first line" is encountered, which indicates a new element definition.
