This class implements the WELL19937c pseudo-random number generator from François Panneton, Pierre L'Ecuyer and Makoto Matsumoto.
This generator is described in a paper by François Panneton, Pierre L'Ecuyer and Makoto Matsumoto Improved Long-Period Generators Based on Linear Recurrences Modulo 2 ACM Transactions on Mathematical Software, 32, 1 (2006). The errata for the paper are in wellrng-errata.txt.

- Constructor Detail
  - Well19937c
```
public Well19937c()
```
    Creates a new random number generator.
    The instance is initialized using the current time as the seed.
  - Well19937c
```
public Well19937c(int seed)
```
    Creates a new random number generator using a single int seed.
    
    Parameters:
    
    seed - the initial seed (32 bits integer)
  - Well19937c
```
public Well19937c(int[] seed)
```
    Creates a new random number generator using an int array seed.
    
    Parameters:
    
    seed - the initial seed (32 bits integers array), if null the seed of the generator will be related to the current time
  - Well19937c
```
public Well19937c(long seed)
```
    Creates a new random number generator using a single long seed.
    
    Parameters:
    
    seed - the initial seed (64 bits integer)
