Add an example loader

Some files are hardcoded. We leave this to future work.
Simplify the code when loading changes into the graph
Delete white spaces and tabulations
Delete the useless commented line when loading changes into the graph
Delete the conditionnal block that does not scan the graph in the order of the input text/english_sentence
Output the second, the third and the fourth colomn of the conll output file
Browse each sentence twice : first to get the index of dependency target of the current token, then to print it when on the current token
show for each token the conll dependency tags instead of their Lima couterparts.
Debug the stop of the AnalysisDumpers

In case a Lima dependency tag is neither in the mapping file nor linked to any Conll tag.
Add hyphen on the last columns in the output file and replace the lemmas on the 2nd column by the tokens
Add the dependency mapping file into the project
Modify the hard-coded path to the mapping file in the source file
Add the SRLLoader source files
Correct the path to the conll input file
