#990 'symbol' not found

[Derrick Oswald]

There seems to be a symbol tree issue, where a find on a recently added element doesn't return it.

The attached file complains about the symbol not found on line 581, yet defined on line 571:
$ gridlabd TRA5200.glm
TRA5200.glm(581): 'KLE470570' not found
FATAL [INIT] : shutdown after command line rejected

However, if lines 571 and 581 are edited to change "KLE470570" to "foo" the file is read correctly.

Attached a patch that work's for me.
