Add physics entry types

I don't expect this to be completey finished until there is a community around PlanetPhysics, however some basic types are needed. Please add suggestions.

Sergiy Pereverzyev (mathforever) suggested the following in PP forums:

I would like to discuss the types which are used for PP-entries. For the moment the types of the entries in PP corresponds to the types used in PM, i.e.

Axiom Corollary Definition Data Structure Result Conjecture Example Biography Topic Application Derivation Proof Theorem Algorithm

Let us group these types according to some criteria.

BASIC THINGS: Axiom Definition Biography Topic

what is missing in the above list is Law - Like Newton's law, Hooke's law, Planck's law, etc…. Experiment - Like Michelson-Morley experiment

DERIVED THINGS: (in the sense that the information located in below types is derived from information in the BASIC)

  Derivation
  Example
  Application

  Theorem
  Conjecture
  Proof
  Corollary
  Result

The types which are ussual for math but probably are not needed for phys:

Data Structure Algorithm

***************************

So, to summarize, one needs Law, Experiment type and could throw "Data Structure" and "Algorithm". There are probably also other types which are specific for phys and I have missed, but Law and Experiment should be added, and some existing entries should be already typed as Law instead of Theorem.

I like the suggestions, but I would not throw away Algorithm for sure, since computational physics can use it. Data Structure is a maybe, but I will keep it around just in case. --bloftin

pbruin suggested adding types physical quantities and units. --bloftin

To add new types I did the following:

1) In Config.pm line 32, I added

use constant LAW=>27;

2) Added entry for single characters to represent types

line 271: 27=>'l'

3) Added typestrings

line 299 27=>'Law'

This is all I did, and need to know if there is more.
