This builds on the support for backslash character escapes in both single
and multicharacter expressions. Backslash character escapes are now
possible with quotations and backslashes, and the same code to interpret
the escapes is applied to both single and multicharacter sequences. |

Updated the #include/#define directives to work properly for nested includes.
(They were supposed to work properly for nested includes before ... and didn't)
This fixes those bugs. |

Added the capability to "see" character's encoded within a binary file,
by printing the character value(s) of each opcode (if they are printable)
on each line. |

Added the capability to look at binary files and 'see' characters as they
are encoded in memory. |

Dhrystone benchmark updates--added the copyright notice. (Oops!) |

Final set of changes finishing the Dhrystone package. Dhrystone, as
implemented by hand in assembly, now works. |

Files added/updated to get Dhrystone benchmark to work. Several fixes
to the CPU in the process, 'cause it wasn't working. Stall-less ALU
ops now work better, to include grabbing the memory result as it comes out
of the memory unit and placing it straight into either ALU or memory unit
for the next instruction. |

A series of updates associated with getting Dhrystone to work. Includes
updates to getting multiple files to link/work together within the assembler,
as well as getting quoted quotations to work in the lexer, and better
include file support in the preprocessor. |

Here's the documentation update to support the pipelined read/writes of
the bus from the CPU, as well as the test file that proved they worked. |

A couple of quick updates:
- The Zip CPU now supports pipelined memory access at one clock per
instruction (assuming all the instructions are in the cache)
- There is now a 'zipbones' module to build a Zip System without peripherals.
Any peripherals would then need to be external to the CPU.
- Some bug fixes.
Documentation changes coming shortly. |

*Lots* of changes to increase processing speed and remove pipeline stalls.
Removed the useless flash cache, replacing it with a proper DMA controller.
"make test" in the main directory now runs a test program in Verilator and
reports on the results. |

I updated the system diagram to reflect the new version that has a direct
memory access controller, rather than the (useless) manual cache. |
