Added FlushF to hazard unit.
...
Fixed some typos with the names of signals in the branch predictor. They were causing signals to be not set. Note there is a modelsim flag which prevents it from compiling if a logic is undefined.
I will look this up and add it to the compiler.

Hacked the sram memory models to reset their internal registers. This allows the simulation to run but is only temporary.
...
About 149307ns of simulation run.

Wrote a bash script to generate custom modelsim radix which maps instruction addresses into human readable lables.
...
Once combined with some simulation verilog this will display the current function in modelsim.

We now have a solid rough draft of the 2 bit sat counter branch predictor with BTB and RAS.
...
This is not yet tested but the system verilog does compile.

added branch predictor 2 bit table + SRAM model. The SRAM model is only approximate, but it does correctly model the read and write pipelined behavior.

The top level of the branch predictor built and compiles. Does not yet function. Missing the BTB, RAS, and direction prediction tables.
