(Constructor)

Creates new transform klass id.
klassSize   : the transform klass structure size.
objSize     : the transform object size.
name        : the transform's name.
href        : the transform's identification string (href).
usage       : the allowed transforms usages.
initialize  : the initialization method.
finalize    : the finmalization (destroy) function.
readNode    : the XML node read method.
writeNode   : the XML node write method.
setKeyReq   : the set key requirements method.
setKey      : the set key method.
verify      : the verify method (for digest and signature transforms).
getDataType : the input/output data type query method.
pushBin     : the binary data 'push thru chain' processing method.
popBin      : the binary data 'pop from chain' procesing method.
pushXml     : the XML data 'push thru chain' processing method.
popXml      : the XML data 'pop from chain' procesing method.
execute     : the low level data processing method used by default
implementations of pushBin, popBin, pushXml and popXml.
Returns     : new transform klass id or None if an error occurs.
