Generate a random graph with desired size, clustering coefficient, and degree distribution

This uses a fast network growth algorithm. It is not an exact algorithm, so the resulting clustering coefficient may differ slightly from the requested value. Users may provide their own R functions to sample from the degree distribution.

Let's generate a random graph with a Poisson degree distribution

```
library(rclustnet)
g <- rclustnet( n=50, CC = .25, rdegdist='pois', lambda = 3 )
plot.igraph( g ,vertex.size=1 , vertex.label=NA)
```

Let's increase the clustering:

```
g <- rclustnet( n=50, CC = .50, rdegdist='pois', lambda = 3 )
plot.igraph( g ,vertex.size=1 , vertex.label=NA)
```

Let's make one with a skewed degree distribution:

```
g <- rclustnet( n=100, CC = .15, rdegdist='geom',prob=.25 )
plot.igraph( g ,vertex.size=1 , vertex.label=NA)
```

Let's make a big one:

```
g <- rclustnet( n=5e3, CC = .3, rdegdist='nbinom', size = 20, prob=.9 )
plot.igraph( g ,vertex.size=0, vertex.label=NA)
```

Note that this took less than thirty seconds to generate.
