fixtancpxpars - SolidsPack - Standardize the parameters of a SolidsPack dataset 
                for use with the panel interface. 
*******************************************************************************

The macro fixtancpxpars is called by the apptype macros solidsseq1d, solidsseq2d
and solidsseq3d when starting an experiment with a standard uppercase setup 
protocol.  This macro fixes the default values and properties of typical parameters
used by solids sequences to avoid problems from legacy datasets. Otherwise uppercase
setup protocols inherit all parameter properties and values from previous datasets.  

For example, the protocol Tancpx resets the standard cross-polarization experiment 
tancpx.c, while retaining the parameter values for the CP module. However, the 
fixtancpxpars macro ensures that the amplitude step size aHhx is .0125 (16 bits) rather 
than 1 (the legacy 13 bits).
