-This module converts code written for Numeric to run with numpy

-Makes the following changes:
- * Changes import statements (warns of use of from Numeric import *)
- * Changes import statements (using numerix) ...
- * Makes search and replace changes to:
-   - .typecode()
-   - .iscontiguous()
-   - .byteswapped()
-   - .itemsize()
-   - .toscalar()
- * Converts .flat to .ravel() except for .flat = xxx or .flat[xxx]
- * Replace xxx.spacesaver() with True
- * Convert xx.savespace(?) to pass + ## xx.savespace(?)
-
- * Converts uses of 'b' to 'B' in the typecode-position of

-   eye, tri (in position 4)
-   ones, zeros, identity, empty, array, asarray, arange,
-   fromstring, indices, array_constructor (in position 2)
