dgrat 58e2ac4e56 Filter: Template implementation for <Filter> 
There are implementations for float, Vector2f and Vector3f for the Low
Pass Filter and the *2p filter.  I tried to implement these filters
with one common template implementation.  This implementation saves
some lines of code and reduced the redundancy.  One could save even
more code if the currently overloaded isinf/isnan functions and checks
can be removed.

Gustavo Jose de Sousa a1af0c2051 Filter: standardize inclusion of libaries headers 
This commit changes the way libraries headers are included in source files:

 - If the header is in the same directory the source belongs to, so the
 notation '#include ""' is used with the path relative to the directory
 containing the source.

 - If the header is outside the directory containing the source, then we use
 the notation '#include <>' with the path relative to libraries folder.

Some of the advantages of such approach:

 - Only one search path for libraries headers.

 - OSs like Windows may have a better lookup time.

Randy Mackay a0369b85d1 LowPassFilter: make methods non-virtual 
No classes inherit from this class so no need for set_cutoff_frequency,
set_time_constant and reset(T) to be declared virtual.  Saves 6 bytes of
RAM.

James Bielman 4fa7bb1486 Add AVR compatibility header for missing math.h definitions. 
- Define float versions of math functions to the double versions
  on AVR (eg. #define sinf sin).
- These macros appear to be missing in older versions of avr-libs.
- Include AP_Math.h rather than math.h to get these definitions.

James Bielman 5631f865b2 Update floating point calculations to use floats instead of doubles. 
- Allows use of hardware floating point on the Cortex-M4.
- Added "f" suffix to floating point literals.
- Call floating point versions of stdlib math functions.

Pat Hickey c56c4ae240 Various example sketches: hal.uart0->begin(115200) is redundant. use console. 
just assume uart0 is initialized by the HAL, because it is. DRY.
also, don't ever use uart0 explicitly in example sketches, use console
and let the hal figure it out.
