Elemental analysis calculation

I function as the next.

* The content rate is calculated from the atomicity.
* The calculation which is nominal composition from the content rate

* Oxygen can't be input because calculation of nominal composition assumes a burning way. The rest is calculated as oxygen from a total of the respective content rates.

That the number of elements which can be chosen about a trial version is even number 20 of atomic number, it's and number 110 of atomic number can be even calculated by a product edition.
Operations check a trial version first, please.

How to use it
------------
(1) It's chosen from the atomicity whether it's calculation of nominal composition from calculation of the content rate or the content rate.
(2) The numerical value is input to each element, and a calculation button is pressed.

Notice
-------------
(1) Operations check
* F12-C (android version 2.3.4)

(2) It's possible to choose even 2 kinds of all except for C,H,N,O,S about the element which can be chosen.

(3) It's removable on a SD card.
