Random field base element generator.
This is a generator of random field elements that can be used with any field. It initializes elements using rand(). For prime fields with p < 2^32, a near-uniform distrubution can be expected. For larger fields or non-prime fields, a near-uniform distribution on an unspecified subset of the elements can be expected.

Constructor from field, sampling size, and seed.
The random field element iterator works in the field F, is seeded by seed, and it returns any one element with probability no more than 1/min (size, F.characteristic(c)). A sampling size of zero means to sample from the entire prime subfield. A seed of zero means to use some arbitrary seed for the generator which will vary from run to run.
| F | LinBox field in which to do arithmetic |
| size | constant integer reference of sample size from which to sample (default = modulus of field) |
| seed | constant integer reference from which to seed random number generator (default = 0) |
