Issue with "'s" in tree_example_ICD10_Chap_VI.txt in example_data

Hello, I wanted to inform you that there is an issue with "'s" in the tree_example_ICD10_Chap_VI.txt in the example_data folder. When running the grs_tree_analysis.R file with the example files given, the dimensions of the results are 122x8 instead of 155x8. We fixed this issue by replacing all "'s" with "s".
