Index of decoders

The codes.decoders object may be used to access the decoders that Sage can build.

It is usually not necessary to access these directly: rather, the decoder method directly on a code allows you to construct all compatible decoders for that code (sage.coding.linear_code.AbstractLinearCode.decoder()).
