Some issues that arose in the first Mt. Spurr run:

   -The original workox file had trace elements as elements rather than rock components. E.g. Pb should be PbO not Pb. Expand workox to address this.

   -Ipun was set to 1 (which is what we want for Chim). It should be 3 initially, and is reset to 4 in subsequent pickup files.

   -Lims was set to 0, so no solid solutions. Lims = 1 to get them.
