In genetics a reading frame is a way to divide a sequence of nucleotides (DNA bases) into a set of consecutive non-overlapping triplets (also called codon). Each of this triplets is translated into an amino-acid during a translation process to create proteins.

In a single strand of DNA you find 3 Reading frames, for example the following sequence:
```
AGGTGACACCGCAAGCCTTATATTAGC
```
will be decompose in:
```
Frame 1: AGG·TGA·CAC·CGC·AAG·CCT·TAT·ATT·AGC
Frame 2: A·GGT·GAC·ACC·GCA·AGC·CTT·ATA·TTA·GC
Frame 3: AG·GTG·ACA·CCG·CAA·GCC·TTA·TAT·TAG·C
```
In a double strand DNA you find 3 more Reading frames base on the reverse complement-strand, given the previous DNA sequence, in the reverse complement ( A-->T, G-->C, T-->A, C-->G).
Due to the splicing of DNA strands and the fixed reading direction of a nucleotide strand, the reverse complement gets read from right to left

```
                        AGGTGACACCGCAAGCCTTATATTAGC
Reverse complement:     TCCACTGTGGCGTTCGGAATATAATCG  
reversed reverse frame: GCTAATATAAGGCTTGCGGTGTCACCT
```

You have:
```
Reverse Frame 1: GCT AAT ATA AGG CTT GCG GTG TCA CCT
reverse Frame 2: G CTA ATA TAA GGC TTG CGG TGT CAC CT
reverse Frame 3: GC TAA TAT AAG GCT TGC GGT GTC ACC T
```

You can find more information about the Open Reading frame in wikipedia just [here] (https://en.wikipedia.org/wiki/Reading_frame)

Given the [standard table of genetic code](http://www.ncbi.nlm.nih.gov/Taxonomy/Utils/wprintgc.cgi#SG1):

```
    AAs  = FFLLSSSSYY**CC*WLLLLPPPPHHQQRRRRIIIMTTTTNNKKSSRRVVVVAAAADDEEGGGG
  Base1  = TTTTTTTTTTTTTTTTCCCCCCCCCCCCCCCCAAAAAAAAAAAAAAAAGGGGGGGGGGGGGGGG
  Base2  = TTTTCCCCAAAAGGGGTTTTCCCCAAAAGGGGTTTTCCCCAAAAGGGGTTTTCCCCAAAAGGGG
  Base3  = TCAGTCAGTCAGTCAGTCAGTCAGTCAGTCAGTCAGTCAGTCAGTCAGTCAGTCAGTCAGTCAG
```
 
The tri-nucleotide TTT = F, TTC = F, TTA = L...

So our 6 frames will be translate as:

```
Frame 1: AGG·TGA·CAC·CGC·AAG·CCT·TAT·ATT·AGC
          R   *   H   R   K   P   Y   I   S
         
Frame 2: A·GGT·GAC·ACC·GCA·AGC·CTT·ATA·TTA·GC
             G  D   T   A   S   L   I   L  
            
Frame 3: AG·GTG·ACA·CCG·CAA·GCC·TTA·TAT·TAG·C
             V   T   P   Q   A   L   Y   *
            
Reverse Frame 1: GCT AAT ATA AGG CTT GCG GTG TCA CCT
                  A   N   I   R   L   A   V   S   P

Reverse Frame 2: G CTA ATA TAA GGC TTG CGG TGT CAC CT
                    L   I   *   G   L   R   C   H

Reverse Frame 3: GC TAA TAT AAG GCT TGC GGT GTC ACC T
                     *   Y   K   A   C   G   V   T
            
```

In this kata you should create a function that translates DNA on all 6 frames, this function takes 2 arguments.
The first one is the DNA sequence the second one is an array of frame number for example if we want to translate in Frame 1 and Reverse 1 this array will be [1,-1]. Valid frames are 1, 2, 3 and -1, -2, -3.

The translation hash is available for you under a translation hash `$codons` [Ruby] or `codon` [other languages] (for example to access value of 'TTT' you should  call $codons['TTT'] => 'F').

The function should return an array with all translation asked for, by default the function do the translation on all 6 frames.
