#2 Initialization bug in lmInterpolation::clprob()

[Jerry James]

Currently, if the extendible parameter to lmInterpolation::clprob() is non-NULL, the local variable _extendible is set to freshly allocated memory. Then, on the very next line, the value false is converted to a pointer (i.e., NULL), then stored in _extendible. The intent appears to have been to initialize the memory that _extendible points to to the value false. This patch makes that correction.
