Improve BatList documentation of exceptions
list: added span function.
Similar to Haskell's, but using BatList's mutable implementation.
Useful for group.
list: added group_nosort function, which performs a non-sorting grouping.
Similar to Haskell's groupBy. Cf. issue #384.
minor mistake in Makefile made test-native run test-byte as well
add an Array1.of_enum function to Bigarray, strengthen Array1.enum specification

In an ideal world we should also provide enum / of_enum pair for
higher-dimensional cases, but in practice most people only use Array1
anyway (to talk with C bindings). Note that enum already exists in the
generic-dimension case GenArray, but the new implementation is better
specified as it guarantees the expected sequential ordering.
list: group_nosort -> group_consecutive.
Documentation notes. Cf. issue #384.
