Improved installation script, especially for environments where ``cython`` or ``numpy`` are not installed.
9.1.3
Minor update: rare-bug fix for `lsqfit.MultiFitter`; new parameter `wavg_svdcut` in `MultiFitter`.
9.1.2
This provides: a minor bug fix in `lsqfit.MultiFitter.chained_fit` concerning `fit.svdcorrection`; and a new keyword `fitname` for the same routine.
9.1.1
Minor bug fix in MultiFitter.
9.1
Adds new class lsqfit.MultiFitter. This provides a framework for organizing complex fits around a small number of user-defined models that are fit simultaneously to many different pieces of data using different sets of parameters. It was developed to support the corrfitter module but is more general.
9.0.2
This fixes the installation instructions but otherwise leaves the code unchanged. Note that GSL, if it is used, must be version 2.2.1 or later.
