Add the assembler guide to the docs list.
Merge branch 'feature-8bitsim' into dev
Changed default line terminator to be compatible with excel so that there are not blank lines in the imported file.
Merge pull request #34 from timburke/feature-8bitsim

PV Logging Module v1.0 and MIB12 Executive Able to Handle Paged Applications
Merge branch 'feature-8bitsim' into dev
Made mib api region a normal psect and link in the right location

- change mib api from an absoluted located psect to a regular one
with a linker flag to put it in the right spot.  This is cleaner,
safer and better.  It also removes the ability of other psects
to inadvertantly stomp over the api.
- change the pic12 build system to pass the right linker flag
to place the the mibapi psect in the right spot
- add mibtool api command that dumps the mib api from a mib12
executive hex file.
- refactor chip specific addresses into pymomo from site_scons
so that they can be shared with mibtool easily
Add default release and test targets to pic12 executive
Modify pic12_executive unit tests to use new mib block format and size.
Remove random blank line from test_summary.py
Fixed momo-commander for compiling on mac os x

- Library paths were incorrect on my macbook
- invalid string comparison, need to use strcmp in C/C++
- cleaned up some code
- needed extra include of stdlib on some platforms
Update pic12 build process to insert hardware type in mib block
Fix mib12_executive bootloader bugs and finish registration

- some bugs crept in during the conversion of the mib12_executive
   from primarily c to primary assembly.  Fixed them and verified
   correct programming on 16lf1847.
- replaced registration function with optimized asm version
   takes up less space and is more robust.  Uses asm memcpy function
   to pull data from application code.
Added more branching macros in pic12 assembly for readability
Rewrote mib spec macro to not use ternary operator

This makes the macro work in assembly code as well as c.
Fixed bugs in pv_module, added debug mib endpoints

There was a random bit being or'ed in with one of the voltage
measurements.  Unclear why I put it there.  I think it was to
test that the fat32 code was write something other than zeros
but it never got removed and only shows up when measuring low
voltages.

Added mib endpoints for sampling v1, v2, v3, i1 for debugging.
Add checksum calculation to mibtool

mibtool checksum <hex_file> calculates the checksum
of the application module pointed to by hex_file in
the same manner as the mib12_executive so that the programmed
rom can be verified.  The application hw type is pulled from
the mib block so it does not need to be specified.
Fixed mibtool documentation to wrap at 80 character lines
Updated mib12 template code to use .mib files
Created modtool to create module skeletons

Can currently call modtool mib12 <name> to create a new
module with the given name in momo_modules/name.  The
module compiles for all known pic12 targets out of the box.
Clean up old scripts that have been replaced

All functionality found in these scripts is now part of
either mibtool, modtool or pcbtool.
