Created initial project skeleton. Added header and source files `lrnd.h` and `lrnd.c` respectively. Filled them in with an initial definition of the `lrnd` struct and the `lrnd_next_value()` function. Also defined constant `lrnd_stdlib_rand` generator that wraps the standard library `rand()` function. Added initial test file `lrnd_tests.c` with a simple test. Created an Autotools build system. Created a readme file and man page. Added a BSD-style license.
